SFC suspends Ku Yuen Leung, ex-BOCOM, for 18 months
SFC, 23-Aug-2016
Our take: Mr Ku had deduced that an algorithmic liquidity provider would take his warrants if he bid for the related shares. Bids cannot be "artificial" as they are binding and capable of being hit. Order queues are not measures of demand and supply, they are just a series of binding bids and asks. A lot of demand or supply is not displayed, including that which buys from the best ask or sells to the best bid. The philosophy behind these prosecutions is flawed; the SFC should not encourage people to expect a directional price signal from the order queues.
